Units meters, glTF Y-up, ground Y=0. GLB is self-contained: 17 embedded images, no external dependencies, no Draco/KTX decoder needed. REPLACE, DO NOT STACK Remove the entire old fleet_hub.glb group AND the entire depot_environment.glb group. This replacement includes all required building, canopy, local concrete pad, bay markings, footpath, perimeter and planting. Do not retain their brick buildings, brick backdrop, old roof, old bay stripes, old fence, old foliage or old props. Keep the host scene's continuous asphalt, actual separately loaded Corolla GLBs, actual separately loaded charger GLBs, hero route, scan effect, lights, HDRI and cameras. No car, charger, continuous asphalt ground, light, or camera is exported here.

These are visualization geometry, not manufacturer models, an engineering design or a claim of structural approval. The operations building and canopy are original fictional designs for this prototype. MATERIAL HANDLING Preserve source materials and photographed maps. Fences and shrubs use glTF alpha MASK with cutoff .45 and doubleSided true. Preserve alphaTest when cloning/fading materials. Do not replace them with opaque flat-color materials. No brick materials are exported. QA Original assembly validation.json records successful re-import, geometry count, coordinate bounds, no external textures, no preview model exports, no brick maps and a clear hero corridor. The original GLB had 74 unique meshes, 320 mesh nodes and approx 318,952 instanced triangles. The operations-only revision appends modified geometry while preserving original source buffer data; Additional instanced three-storey architectural details are appended by the operations revision.

The Corolla is the approved prototype stand-in, not a claim that a Corolla is an EV. Preview ground and sunset illumination use previously obtained Poly Haven photographic asphalt/HDRI assets from ../lighting_assets, CC0. They are not embedded in the runtime environment GLB. 2026-10-01 THREE-STOREY OPERATIONS BUILDING REVISION Replaces the prior enlarged blank upper wall with a three-storey corporate operations building. Original operations nodes 76–113 are rebuilt; shared upper-floor window, sill, mullion, slab-band and structural-slab nodes are appended. All original non-operations nodes, mesh definitions, materials, textures and embedded buffer bytes remain unchanged. The original ground-floor photographed windows and human-scale entrance remain; upper floors reuse the licensed photographed Poly Haven window geometry and PBR materials already credited above. Geometry is opaque physically lit architecture; no unlit glTF extension. Primary facade footprint remains 14 x 7.8m. Roof coping reaches 9.6m, with original physically sized HVAC equipment up to 9.963m. Two repeated upper-floor window rows, window sills/mullions and horizontal slabs make the three storeys explicit. Shared window and box meshes avoid duplicated texture payloads. Added facade details extend the building's side envelope only to x=-2.71 and x=12.71; car route, canopy and perimeter remain clear. Official user-provided public/brand/zaptric-logo-white.png is aspect-preserved on an opaque blue 6:1 facade panel with OPERATIONS labeling. The company logo is not covered by the CC0 architectural-source licenses above. Low facade placement keeps branding prominent even where the unchanged close arrival camera crops the upper floors. Modest emissive PBR, no external image dependencies. Original entry awning and doors retain human-scale heights. Fleet vehicles and driver are separate assets and unchanged by this revision. Reproduction: python visual-source/enlarge-brand-operations.py --source-ref d97d599 (Pillow and numpy). Reconstructs from immutable pre-edit git source without stacking changes. Offline re-import and composition renders use exact runtime camera/route samples with approximate lighting; they do not constitute browser/WebGL verification. 2026-10-01 REALISTIC OPERATIONS FACADE REFINEMENT Supersedes the facade portions of the three-storey revision above. Existing original buffer bytes and all non-building nodes are preserved byte-for-byte. Replaces the former stretched wall planes, factory openings, cladding ribs and proud upper windows with actual facade openings, physically dimensioned light textured concrete piers, grey rainscreen spandrels, recessed solar-control glass and aluminium frame/mullion assemblies, individual sill/drip profiles and slim floor edges. The concrete facade uses the already embedded CC0 Poly Haven Concrete Floor Worn 001 maps credited above; no new third-party textures are added. New glazing, frames, panels, entry canopy, dark lobby backing, door pull handles, roof heat-pump units, louvres and service tray are original visualization geometry/materials. No manufacturer affiliation or engineering/accessibility certification is claimed. The ground entrance retains an approximately flush threshold on the existing low walkway without introducing steps. Original official Zaptric sign and image payload remain unchanged. Three storeys and the original 14 x 7.8 m primary wall footprint, 9.6 m roof coping and 9.963 m original HVAC maximum are retained. Facade projections are modest and remain behind the existing walkway. Original canopy, fence, planted edges, bay paint and all other non-building site content are unchanged. Reproduction: python visual-source/refine-operations-facade.py --source-ref a688070 Validation: visual-source/operations-facade-qa/report.json and solids.json. The build asserts byte-for-byte original buffer preservation and unchanged non-building nodes. visual-source/render-operations-facade-qa.py renders actual output geometry with exact runtime camera and per-frame FOV from scripts/test-fleet-camera.cjs (CAMERA_FRAMES), plus a labelled detail view. Lighting, ground shading and color management are offline approximations; no browser/WebGL output is claimed by those images. 2026-10-03 editable-scene candidate: larger EV service facility Original project-authored service-wing geometry is reproducible with visual-source/scene-review/build-hub.py from source commit 2dd1ceb302e563bf00603ecb39c5b22524600247. The 18 x 11 m wing has three 4.6 m clear-width, 3.6 m clear-height bay openings, recessed interiors, retracted lift arms, workbenches, tools, luminaires, standing-seam roof, roof equipment, gutters, a marked approach and visitor parking. Retained concrete/metal materials and fence meshes retain the CC0 provenance documented above. No new third-party model, texture, or Terminal Industries asset was downloaded or copied. Terminal's public website was a composition and working-yard reference only. The two rendered Operations signs and their old gate board were removed; official Zaptric marks elsewhere retain their original brand ownership. This is visualization geometry, not a certified building/engineering design. 2026-10-03 scene-review pass 2 (following b7e2ec5): the original service wing is refined to 15.2 x 11 m with three 4.3 m clear openings. Existing CC0 concrete PBR maps are reused for slabs/apron; original joints, drainage, equipment, lights and a relocated tree bed are added. Only superseded east garden-border faces are removed from the original concrete batches; all other faces and original encoded buffers are retained. The deterministic prepare-hub-base.cjs and build-hub.py sources document these changes. 2026-10-03 expanded fleet-hub review: original service hall grows to 20.1 x 14.5 m with four full-width service bays (+74.3% floor area). Original project-authored bay guides, wheel stops, outlets, rear equipment strips, parts shelves and inspection bench are added. Retained licensed CC0 materials and factory/chainlink components keep their original attribution. East/rear fence segments move outside the expanded footprint. Operations lettering remains removed. No new external asset or brand is introduced.
